In enzymology, a N-carbamoylputrescine amidase (EC 3.5.1.53) is an enzyme that catalyzes the chemical reaction

N-carbamoylputrescine + H₂O $\rightleftharpoons$ putrescine + CO₂ + NH₃

Thus, the two substrates of this enzyme are N-carbamoylputrescine and H₂O, whereas its 3 products are putrescine, CO₂, and NH₃.

This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N-carbamoylputrescine amidohydrolase. Other names in common use include carbamoylputrescine hydrolase, and NCP. This enzyme participates in urea cycle and metabolism of amino groups.
